---From testing I did on my trigear, I concluded there is no tank drain
arrangement which will remove all hazardous quantities of water in
ground attitude. The two tank drains I have (which pick up from the
fwd part of each tank saddle) will have psychological value only.
What I did then was fabricate a 9 oz. sump, which attaches to the
outlet of the floor-mounted (old style) selector valve arrangement;
two fuel lines from it feed the 914 fuel pumps. It has a drain valve
accessible from the bottom of the aircraft. However, a gascolator of
healthy capacity should accomplish similar results, though not meet
FAA rules for production aircraft, as it's neither a sump nor min. 8
oz. capacity.
